Determining control variables before map input

, ,
1

Hello all,

we often manipulate Control variables on certain fields either to protect them, make them input fileds, with intensity… etc.

How is it possible within a module before input to a map to see what is contained in the control variable, in other words, whether the control variable is intensified, input, modifiable, protected, displayed, not displayed etc…

eg .

i could do this

01 #data-cv (C)

move (ad=ON) to #data-cv /* making the data output, non-display

input map ‘testmap’

later if I need to check the control variable before seeing what it does to the field on the map (before input map)

How is it possible to see what is in #data-cv?

Many thanx

REDEFINE a Control Variable as format B2.

Control Variables are bit encoded.

Write yourself a little program with code like:

DEFINE DATA LOCAL
1 #CV (C)
1 REDEFINE #CV
2 #CV-B (B2)
END-DEFINE
*
MOVE (CD=RE) TO #CV
WRITE #CV-B
etc.

You will have a table of values for every possible value for #CV

Then check #CV-B for the value(s) you are interested in.
